Clipping glitch on models
Go to Viewport shading &gt; Click the arrow &gt; Disable Backface Culling

But if you are also exporting to game engine:
Select object &gt; Go to edit mode &gt; select everything (Press &quot;A&quot;) &gt; Go to Mesh (left top part of the viewport)&gt; Normals &gt; Recalculate outside

EDIT: Game Engines have the backface culling &quot;locked on&quot; thats why you need to rotate normals as shown above
